To a mixed solution of the compound (0.038 g) obtained in Example 783, the compound (0.023 g) obtained in Step 3 and ethanol (1.0 ml) was added N,N-diisopropylethylamine (0.019 ml) at room temperature. After stirring at 100° C. for 3 hr, the reaction mixture was concentrated under reduced pressure, and the residue was purified by thin layer silica gel chromatography (methanol:chloroform=1:9) to give the title compound (0.032 g).
